This application killed practically all the vegetationpermanently with the exception of some of the roots of the w Electric /ii/.Jonrmil Star-Shaped Concrete Pole, Showing Character of Rein-forcement and Provision for Conduit eliminating the cost and maintenance of metal spikes. Thenew pole is designed to utilize a minimum amount of con-crete, which is compressed into metal molds so constructedthat the steel reinforcement is absolutely held in its properposition until the initial set has occurred. The concrete ismerely a protection for the fabricated steel reinforcement,which is figured to develop the entire strength of the features claimed for these poles are freedom fromexposed metal parts, superior flexibility and greater sta-bility against wired pressure owing to the bearing of thesaw-buck section against the earth. The following table is the makers comparison of thispole with square reinforced and round wooden poles.

This operation will be repeated very soon, afterwhich the company claims that all vegetation will be entirelyextinct. By this method the railway company feels that itcan keep its lines free from weeds at considerably less ex-pense than it has been able to do with the methods previ-ously employed. In the foregoing table the word square refers to ordinarvconcrete poles with a square cross-section reinforced withvertical steel bars and poured into the top of vertical woodenforms erected in place ;
